Tuner Expects -d64 Option for Linux 64–Bit JVM (6797035)

Description

When the Linux AMD 64–bit JDK is used without the -d64 option, the server runs as a 64–bit server. However, without the -d64 option, the Tuner does not allow the maximum heap memory to be set above 1400 MB.

Workaround

Add the -d64 option as a JVM option to the server or cluster you wish to tune. To use the Admin Console, go to the JVM Settings page for the configuration, select the JVM Options tab, select the Add JVM Option button, and enter the -d64 option. Or use the asadmin create-jvm-options command. For example:

asadmin create-jvm-options --target server \\-d64

For more information about the asadmin create-jvm-options command, see the Sun GlassFish Enterprise Server 2.1 Reference Manual.
